SPW replacement WRCLIK-TR transmitter for Hunter WRCLIK/WRFCLIK - grey/white transmitter-only, easy pairing

This is the SPW replacement WRCLIK-TR transmitter for Hunter WRCLIK and WRFCLIK rain/freeze sensor systems — transmitter only, requires pairing with your existing receiver.

If your rain or rain-and-freeze sensor stopped communicating, you don’t always need a full kit replacement. This product is a transmitter-only unit intended to substitute the original WRCLIK transmitter and restore wireless signaling to a compatible Hunter receiver. It arrives unpaired and must be addressed (paired) to your existing receiver before it will operate; follow the manufacturer addressing steps and allow the sensor’s internal hydrostatic disks to dry before testing.

How do I get this replacement transmitter working with my receiver?

Pairing (or addressing) is required to link this transmitter to your receiver. The sensor must be dry and the test spindle able to be pressed so the red LED will flash during the addressing process. If the LED does not light, place the sensor in sunlight with the vent fully open until the internal components dry.

• Confirm your receiver is compatible with WRCLIK/WRFCLIK transmitters (not compatible with dangling-wire antenna receiver types).
• Allow the sensor’s hydrostatic disks to dry fully before testing or addressing.
• Press the test spindle; the red LED should flash to indicate readiness to pair.
• Search “WRCLIK Addressing” online for step-by-step illustrated instructions.

What troubleshooting steps help if the transmitter LED won’t light?

Often the LED stays off because the sensor was factory-tested and remained moist in transit. Drying the unit and exposing it to sun with the vent open usually restores normal function. If the LED still does not flash after drying, reach out for support rather than returning immediately.

• Open the vent fully and set the sensor in direct sunlight to speed drying.
• Wait until the hydrostatic disks are dry and the test spindle moves freely.
• If problems persist, contact the seller for guided troubleshooting before initiating a return.

Will this transmitter work with my current Hunter rain or freeze receiver?

This unit is designed to work with WRCLIK (rain only) and WRFCLIK (rain + freeze) receiver systems, replacing the transmitter side only. It is not compatible with older or different Hunter receivers that use an exposed dangling-wire antenna; those setups require purchasing a full replacement kit.

• Compatible: receivers designed for WRCLIK or WRFCLIK protocols.
• Not compatible: receivers using dangling-wire antenna designs — full kit recommended.
• Verify compatibility before purchase to avoid unnecessary returns.

What should I expect after installation and pairing?

Once properly addressed to your receiver, the replacement transmitter will resume signaling rain and/or freeze conditions to your irrigation controller, allowing the controller to suspend scheduled watering as intended. Regularly inspect the sensor and vents for debris and ensure it can dry after rain events to maintain accurate performance.

• After successful pairing, test the transmitter by activating the test spindle and observing receiver response.
• Keep vents clear so the sensor can dry and reset between wet events.
• Contact support if signal range or responsiveness seems reduced.

Who is this for: This replacement transmitter is for homeowners, landscapers, and irrigation techs who already own a compatible Hunter WRCLIK or WRFCLIK receiver and need to replace a failed transmitter without buying a complete new sensor kit. Choose this unit if you can verify receiver compatibility and are comfortable following addressing steps or seeking quick help from the seller when needed.
